Node-aware partition distribution - For efficiency reasons, the Couchbase Kafka Connector 3.0 uses the Couchbase Server cluster map to send DCP stream partitions to Kafka tasks so that they use the smallest number of DCP socket connections.

Connector maintains replication state and can resume streaming from where it left off after a temporary disconnection.

SSL support - You can enable SSL support by simply setting a configuration property.
(KAFKAC-52)

Bulk mode for snapshot transmission - You can now enable bulk mode for DCP Snapshots, so that the offsets are only committed in Kafka once the entire snapshot is received.
This avoids creating duplicates caused by retransmission of mutations in more than one DCP snapshot.
